Which of the following is a function of a personal pronoun?

A personal pronoun serves the function of replacing a noun in a sentence, which helps to avoid repetition and makes the writing smoother and more concise. For example, instead of saying "Maria went to the store because Maria needed milk," one can say, "Maria went to the store because she needed milk." The use of the personal pronoun "she" effectively replaces the noun "Maria," making the sentence clearer and less cumbersome.

The primary role of personal pronouns, such as "I," "you," "he," "she," "it," "we," and "they," is to stand in for specific people or things in a discussion, allowing for more fluid communication. This function is essential for maintaining clarity and brevity in both spoken and written language.
